Wiener
设计一维纳滤波器
(1)产生三组观测数据：首先根据s(n)=a s(n-1)+w(n)产生信号s(n)，将其加噪（信噪比分别为20dB,10 dB，6 dB），得到观测数据x1(n), x2(n), x31(n).
(2)估计xi(n)，i=1,2,3的AR模型参数。假设信号长度为L，AR模型阶数为N，分析实验结果，并讨论改变L,N对实验结果的影响。
(A Wiener filter design (1) to produce three sets of observations: first generating a signal s (n) according to s (n) = as (n-1)+w (n), to add noise (20dB SNR, respectively , 10 dB, 6 dB), to obtain observational data x1 (n), x2 (n), x31 (n). (2) estimate xi (n), i = AR model parameters 1,2,3. Assuming the signal length L, AR model of order N, analysis of experimental results and discuss the impact changing L, N of the experimental results.)

1）利用CC++语言实现给定的LFSR；
2）通过不同初始状态生成相应的序列，并观察它们的周期有什么特点；
3）利用生成的序列对文本进行加/解密（按对应位作模2加运算）。
给定的LFSR为：(1) the use of C C++ language given LFSR
2) to generate the corresponding sequences by different initial state, and observe what are the characteristics of their cycle
3) using the generated sequence of text encryption/decryption (press the corresponding bit for modulo-2 addition operation).
LFSR given as follows:)

说明： 基于灰色预测，指数平滑预测的几个MATLAB程序，对于预测类问题的数学建模，可以说是必备程序。我的导师给我传的。
funesm1,2,3分别为一二三次指数平滑预测程序
fungry为灰色预测程序
funcoef为时间序列预测程序
pudn为广大的编程爱好者提供了一个交流的平台，我在此先谢谢网站的工作人员，我也会努力编出好的程序，一起同大家分享。(Based on Gray predicted that the number of exponential smoothing forecasts MATLAB procedures, issues for the prediction of the mathematical modeling, can be said to be an essential procedure. My mentor gave me spread. funesm1, 2,3 were 123 times procedures fungry exponential smoothing forecast procedures funcoef gray prediction for time series forecasting procedures for pudn programming for the majority of fans provided a platform for exchange, I would like to thank the site staff, I will strive for a good program, to share together.)
